; @Title: Flash declaration for NXP MWCT101x internal flash
; @Description:
; Script arguments:
; DO mwct101x [PREPAREONLY] [CPU=<cpu>] [DUALPORT=<0|1>] [MASSERASE]
; PREPAREONLY only declares flash but does not execute flash programming
; CPU=<cpu> selects CPU derivative <cpu>
; DUALPORT=<0|1> use dual port memory access, default 0
; MASSERASE forces mass erase of device before establishing debug
; connection
; Example:
; DO ~~/demo/arm/flash/mwct101x PREPAREONLY
; Note:
; This file must NOT be modified.
; This file is intended to stay within TRACE32 installation.
; Usage examples are available in the ~~/demo/arm/hardware/... subdirectories.
;
; List of MWCT101x derivatives and their configuration:
; CPU-Type ProgFlash
; [Byte]
; --------------------------------------------------------------------------------
; MWCT1014S 512 KB
; MWCT1015S 1024 KB
; MWCT1016S 1536-2048 KB
;
; The range 0x400--0x40f is guarded against modification.
; Address-Range Description
; --------------------------------------------------------------------------------
; 0x400--0x407 Backdoor Comparison Key
; 0x408--0x40b Program flash protection bytes
; 0x40c Flash security byte
; 0x40d Flash nonvolatile option byte
; 0x40e EEPROM protection byte
; 0x40f Data flash protection byte
;
; Modifications can be done using the FLASH.AUTO command with /CENSORSHIP option.
